An efficient one-pot process for the synthesis of 3-substituted phospholanes and alpha,omega-bisphospholanes was developed. The method involves the replacement of aluminium in aluminacyclopentanes, prepared in situ by catalytic cycloalumination of alpha-olefins and alpha,omega-diolefins, by phosphorus atoms on treatment with dichlorophosphines (R'PCl2). Hydrogen peroxide oxidation and treatment with
开发了一种有效的一锅法合成3-取代的膦酸酯和α,ω-双膦酸酯。该方法包括在二氯膦(R'PCl2)处理下,用磷原子代替通过α-烯烃和α,ω-二烯烃的催化环铝烷基化而制得的铝环戊烷中的铝。用过氧化氢氧化并用S8处理合成的膦酸酯和α,ω-双膦酸酯,得到相应的3-烷基(芳基)-1-烷基(苯基)膦烷1-氧化物,3-烷基(芳基)-1-烷基(苯基) )膦环烷1硫化物,双膦环烷1,1'-二氧化物和双膦环烷1,1'-二硫化物的定量收率差不多。络合物LMo(CO)5(L = 3-己基-1-苯基膦烷,3-苄基-1-甲基膦烷,1,2-双(1-苯基膦基-3-基)乙烷和1,通过3-取代的膦酸酯和α,ω-双膦酸酯与六羰基钼的反应制备6-双(1-苯基膦基-3-基)己烷。通过多核(1)H,(13)C和(31)P光谱证明了配合物的结构。
